Do you think shims on the rails would help at all?
asked by: Noreen
Sliders are noisy especially when compared to a fixed hitch. The first thing you will want to do is pull the hitch out of the rails and make sure the rail hardware is tight. Then make sure all of the hardware on the hitch itself is tight. This is to eliminate the rails and hitch head as the culprit.
If the noise is happening when you are not using the hitch then some shims would probably help some. When using the hitch, the weight of the trailer should take out any rattling.
If the noise is happening during starts and stops with a trailer attached then you are experiencing what is called chucking. This occurs most severe on hitches that have a slide bar type of jaw. Double jaws are more secure, and a wrap around jaw, like that on # RP30084 that you referenced, are the most secure.
Also, make sure your hitch is locked into position when traveling. Even when locked, if there is no weight on it, the hitch can rattle some. The only way to completely eliminate the noise is to take out the hitch when not using it.
